在 Ubuntu 中启动时运行 Python 脚本 [英] Run Python script at startup in Ubuntu

问题描述

我有一个需要在启动时运行的简短 Python 脚本 - Ubuntu 13.10.我已经尝试了我能想到的一切，但无法让它运行.脚本:

I have a short Python script that needs to run at startup - Ubuntu 13.10. I have tried everything I can think of but can't get it to run. The script:

#!/usr/bin/python
import time
with open("/home/username/Desktop/startup.txt", 'a') as f:
    f.write(str(time.time()) + " It worked!")

(实际脚本有点不同，因为我只是将其用于测试目的，但您明白了.)

(The actual script is a bit different, as I'm just using this for testing purposes, but you get the idea.)

我已经尝试了以下所有方法，但没有成功:

I've tried all of the following, with no luck:

• 将命令python startuptest.py放在crontab中，作为@rebootpython/home/username/Documents/startuptest.py，作为普通用户和sudo

• Put the command python startuptest.py in crontab, as @reboot python /home/username/Documents/startuptest.py, both as the regular user and as sudo

将命令 python/home/username/Documents/startuptest.py 放在 /etc/rc.local

打开 Ubuntu 的启动应用程序并将命令放在那里

Opened Ubuntu's Startup Applications and put the command there

完成上述所有操作，将命令放入shell脚本中并改为调用该 shell 脚本

Done all of the preceding, putting the command into a shell script and calling that shell script instead

没有任何效果.我觉得我错过了一些简单的东西.有任何想法吗?(如果我只是从终端运行命令，脚本运行良好.)

Nothing works. I get the feeling I'm missing something simple. Any ideas? (The script runs fine if I just run the command from a terminal.)

推荐答案

说明

• 将python文件复制到/bin:

  Instructions

  • Copy the python file to /bin:

    sudo cp -i/path/to/your_script.py/bin

    添加新的 Cron 作业:

    Add A New Cron Job:

    sudo crontab -e

    滚动到底部并添加以下行(在所有 #'s 之后):

    Scroll to the bottom and add the following line (after all the #'s):

    @reboot python/bin/your_script.py &

    &"行尾表示该命令在后台运行，不会停止系统启动.

    The "&" at the end of the line means the command is run in the background and it won’t stop the system booting up.

    测试一下:

    sudo reboot

    • 将此文件添加到您的桌面:test_code.py(运行它以检查它是否适合您)

    • Add this file to your Desktop: test_code.py (run it to check that it works for you)

    from os.path import expanduser
    import datetime
    
    file = open(expanduser("~") + '/Desktop/HERE.txt', 'w')
    file.write("It worked!
    " + str(datetime.datetime.now()))
    file.close()
    

  • 运行以下命令:

  • Run the following commands:

    sudo cp -i ~/Desktop/test_code.py/bin

    sudo crontab -e

    添加以下行并保存:

    @reboot python/bin/test_code.py &

    现在重新启动您的计算机，您应该会在桌面上找到一个新文件:HERE.txt

    Now reboot your computer and you should find a new file on your Desktop: HERE.txt
